Casting bits, anyone? Yeah, I thought so, too. Tonight, a gleek and a Stoolbend regular heads to politics, and skitters prepare to be told to be not told what they can't do. (I know. I can word that much better.) But first, some stability in a singing show:

Not all titles featured on BuddyTV are available through Amazon Prime.

L.A. Reid is staying with The X Factor: this comes after a night-long shake-up that saw judges Paula Abdul and Nicole Scherzinger, as well as host Steve Jones, leave the Fox singing competition. The Epic Records chair has signed on for a second season, according to The Hollywood Reporter: not much of a surprise since Simon Cowell does need some serious record label backing if his show is to stay vaguely credible. No further word on who else takes over as new judges, although there are rumors (probably planted?) that Beyonce's being offered a hundred million dollars to join the show. Still, watch this space.

Sanaa Lathan and Jonathan Groff are headed to Boss:Deadline reports that the two theater vets have signed on as regulars for the second season of the Kelsey Grammer drama. Lathan, who currently voices Roberta on The Cleveland Show, will play Tom Kane's new chief of staff Mona; Groff, perhaps best known as Jesse St. James on Glee, will play new staffer Ian Todd.

Beau Bridges is headed back to White Collar tomorrow night: he last appeared in last year's midseason finale as Agent Kramer, Peter's (Tim DeKay) mentor during his early FBI years. Now he's got his eyes trained on Neal (Matt Bomer), which should ruin some Neal/Sara reunion time:

Nancy Grace, say hello to the Chances: the HLN host (and Dancing with the Stars contestant) will make her acting debut on the season finale of Fox's Raising Hope. "This is the first time I've ever gone to a set and acted," she tells TV Guide, adding that she's playing a version of herself. A return to the blue dots from last season? Likely.

Terry O'Quinn faces the skitters: the Lost veteran (and current Hawaii Five-0) guest is headed to TNT's Falling Skies, according to Entertainment Weekly. He'll appear in the second season's last two episodes as a former history professor and mentor to Noah Wyle's character. Will O'Quinn be fighting the skitters like his fellow professor is doing? We're not very clear on that yet.

Bobby Cannavale joins Boardwalk Empire: the Third Watch regular has snagged a regular role on HBO's acclaimed series as Gyp Rosetti, a "charming but ruthless gangster" who'll pose as a threat to Nucky (Steve Buscemi), according to THR. Cannavale is also slated to appear on the upcoming season of Showtime's Nurse Jackie.

Patton Oswalt becomes something like Steve Wozniak: the comedian is headed to CBS' Two and a Half Men as Walden's (Ashton Kutcher) former business partner, according to EW. In the words of the show's writers, he's "the Wozniak to Walden's Jobs." Oswalt, who last appeared in just-cancelled cable comedies United States of Tara and Bored to Death, is only signed on to appear in one episode. At least this means we won't miss his tweeting on Downton Abbey.

The Fonz gets ready for an all-nighter: Henry Winkler will be joining NBC's Up All Night as Robert, Ava's (Maya Rudolph) dad. Will he be as crazy as her? Executive producer Emily Spivey tells TV Guide that he's quite the opposite: "even though he's flighty and a little irresponsible, he's a creative type who writes children's books." His character should debut around late April or early May.

Franklin and Bash gets a slice of American Pie: Chris Klein will appear in one episode of the TNT series as an old high school buddy of Peter's (Mark-Paul Gosselaar) who happens to be a politician -- albeit someone who wants out because of family issues. Also guesting on the show is Nurse Jackie's Paul Schultze, EW reports. Mmmm, pie.
